The motion modeling of the simulated missile-target encounter (SME) of is an important approach for improving the accuracy of missile on-line firing. The designed measurement system of the spatial SME of certain experimental base based on mathematical modeling method of the two three dimensional coordinate transformation is researched. With the help of the background difference principle, the method which movement region is achieved from the dynamic image (MRDI) is determined, as the result, the circumscribed-rectangle center of movement region can be selects as the characteristic testing point. Meanwhile, by bit collection of motion video, using visional CCD imaging technology, image manipulation is realized, then applying the noiseful methods and the bit signal processing technology, motion object and its center coordinate is caught by MRDI method. Furthermore, SME motion parameters are collected by SME measurement system and analyzed theoretically, and the established simulating motion model compared with the experimental analysis, accuracy of measurement system can is satisfied with engineering requirement.
